In this book, authors Caroline S. Clauss-Ehlers, Gargi Roysircar, and Scott J. Hunter provide in-depth coverage of APA's 2017 Multicultural Guidelines, teaching students and professionals how to apply them in clinical practice, education, research, and consultation. As codevelopers of the guidelines, they expand the scope of the original document to create an even more thorough and easy-to-read advice for developing cultural competence. This book takes an ecological approach that considers factors at multiple levels, ranging from small groups to large organizations to societal and cultural forces to historical changes. Chapters dive deep into each of the ten guidelines, reviewing key research findings and offering expert advice for applying them. Each chapter opens with a case study that is revisited throughout the text and is accompanied by discussion questions that promote critical thinking and self-reflection about the importance of identity and intersectionality. The overarching goal is to help people better understand one another, create constructive dialogues about social identity, and guide psychologists to create more fruitful working relationships with clients, patients, students, and others from diverse backgrounds.
